Sycamore Assassin Bug - Pselliopus cinctus

Sycamore Assassin Bug - Pselliopus cinctus

I feel a little guilty posting so many pictures, but this a great service for a layman like myself, sorry.
My Insects of Kansas book shows one almost like this as Pselliopus cinctus. Can this be confirmed?

Moved from Pselliopus.

Sycamore Assassin Bug
I checked with Richard Grantham at OSU and he compared the photo with all of their species and he says P. cinctus.

And don't feel guilty about posting images. The more images you post the more knowledge we gain and the better we get at identifying and understanding insects - and the better this beautiful photo guide of Troy's gets! (Although he may have to quit his day job soon in order to keep up!! :)

Charles, I agree, Pselliopus
Charles, I agree, Pselliopus cinctus. I'm always a little surprised to see these posted as predominantly brown bugs, because around here they are usually bright orange. But the shape of the prontum and other features, and especially the banding on the legs and the lower part of the antennae is diagnostic. I seem to recall that even the piercing mouthparts are banded black and white!

Genus alone is an accomplishment:-)
Folks, just getting the genus right is HUGE! Remember, this site is mostly designed for a lay audience. Plus, the nomenclature today won't be the classification tomorrow. You'd be amazed how many changes I have found that are either very recent, or anticipated, or how many disagreements there are depending on which authority you consult. We're doing great!

Color of Pselliopus, species other than cinctus, moved to guide
Most of the ones I see are brownish-orange, with an occasional bright orange individual. I wonder if it is fading with age--adults overwinter. We should check dates on photos. Or it could be a species difference--P. cinctus and P. barberi are listed for here in North Carolina, about equally common. I haven't seen a key anywhere. Of course, could be a sex difference, or just variability.

So again, based on the North Carolina State University Entomology Collection, there are two species present in the east: P. cinctus and P. barberi. P. barberi, cinctus, and latiofasciatus are on a list for Oklahoma.

Great photos--very crisp and well lit, always a pleasure to see your work. What's your reference book on Kansas Insects?

I'll go aheand and move this to guide page for Pselliopus.

Assassin Bug
Thanks Stephen.
The Kansas book shows it as brown. Who knows.
